19 firefighters have been killed in a wildfire in Arizona. The death toll is the greatest loss of life among firefighters in the US in 80 years.

The men, known as the ' Hotshots', were specially trained to deal with large wildfires. They were believed to be creating an escape route when they were overcome by the fire.

Residents of Prescott, Arizona attended a memorial for the 19 firefighters who died battling a fast-moving wildfire on Sunday. About 200 additional firefighters are now fighting the blaze, which has burned 13 square miles. (July 2)
